A two-capture removal model was used to estimate, within 10 river basins across the United States, proportional fish species richness from one-pass electrofishing and probabilities of detection for individual fish species. Mean estimated species richness from first-pass sampling ([pcirc], s1) ranged from 80.7% to 100% of estimated total species richness for each river basin, based on at least seven samples per basin. However, [pcirc], s1 values for individual sites ranged from 40% to 100% of estimated total species richness. Additional species unique to the second pass were collected in 50.3% of the samples. Of these, cyprinids and centrarchids were collected most frequently. Proportional fish species richness estimated for the first pass increased significantly with decreasing stream width fo...}, number={1}, journal={TRANSACTIONS OF THE AMERICAN FISHERIES SOCIETY}, author={Meador, MR and McIntyre, JP and Pollock, KH}, year={2003}, month={Jan}, pages={39–46} }
